The fabrication scene is booming, and a lot of enthusiasts are now creating custom door panels, stunt walls, and other large fiberglass boxes that showcase speakers in special ways. We have developed custom rings so that fabricating will be easier, and you will have a much better fitment for any 6, 8, 10, and 12-inch speaker you choose. These rings have custom stamped DS18 inlays on the rings and are easily molded in any custom fabrication work.
